So what are actual sys. req. for sims 3 and 4?

[iNanox]

For the sims 3 they say:
2.4 GHz P4 processor or equivalent
1.5 GB RAM
128 MB Video Card with support for Pixel Shader 2.0
For the sims 4 they say
AMD Athlon 64 Dual-Core 4000+ or equivalent
2GB RAM
128 MB of Video RAM and support for Pixel Shader 3.0
i tried this on my old pentium 4 3.4ghz ht with 3gb ram and 256mb video card for sims 3 and it didnt work...i mean it did but like on 10 fps all the time sometimes dropping to 1 fps..
So i tried on my more modern pc with 2gb ram core 2 duo 2.2ghz and 512mb video card..well it works but you need to lower the settings down alot(loading times are longgg even with SDD installed)
now for sims 4 like it says amd athlon 64 4000+ or equivalent so i tried 6000+ i had laying around with 1gb gddr5 video card and well it works but when u move around it laggs alot
so my question is will Intel Celeron G1840 in combo with Radeon R7 250X be enough to run both sims 3 and 4 on medium/high settings?
and also tell me what ur using to play sims 3 and 4 i mean what kind of hardware ty happy holidays <3
